You expect a little more from your sandals than just a thin barrier of rubber between feet and the ground. Keen ups the ante with the Women's Rose Sandal, a feminine fit sandal not afraid of trekking through a little water. A washable synthetic and polyester upper straps in your feet with a webbing system designed to disperse even pressure over the entire foot, rather than pinch certain areas. An adjustable hook and loop strap further customizes the Rose's fit by securing the heel. Both the mesh upper lining and the EVA footbed have been coated with an Aegis antimicrobial shield to block odors by eliminating the bacteria which cause them. For incomparable support, Keen crafted the EVA footbed with an internal, metatomical system in layman's terms, this means an anatomical arch engineered to cradle the natural contours of the foot, especially the arch.
